BackgroundIn the United States, the obese population has increased markedly over the last four decades, and this trend continues. High patient weight places additional stress on TKA components, which may lead to increased polyethylene wear, osteolysis, radiolucencies, and clinical failure. Metal-backed tibial components and all-polyethylene tibial components in the general population have comparable osteolysis and failure, but it is unclear whether these components yield similar osteolysis and… 

All-Polyethylene versus Metal-Backed Tibial Components in Total Knee Arthroplasty.

With modern implant design and instrumentation, rising utilization of TKA along with current and future economic strain on health care, the increased use of APT implant could result in massive savings without sacrificing positive patient outcomes.

All-Polyethylene Versus Metal-Backed Tibial Components-An Analysis of 27,733 Cruciate-Retaining Total Knee Replacements from the Swedish Knee Arthroplasty Register.

These less expensive all-polyethylene tibial components can be safely and effectively used in total knee arthroplasty and were at least as good as or superior to metal-backed tIBial components with respect to implant survivorship at ten years in cruciate-retaining total knee replacements.

Comparative Survivorship of Different Tibial Designs in Primary Total Knee Arthroplasty.

All- polyethylene tibial components were associated with better outcomes than metal-backed modular components, and obese patients may have superior results with all-polyethylene and posterior-stabilized components.

All polyethylene tibia - results of functional and radiological outcome at 5 years follow-up

APT components have good to excellent functional outcome and good radiological outcome at 5 years and are safe in view of radiologic component migration at 5-year follow-up.

All-polyethylene Tibial Components are Equal to Metal-backed Components: Systematic Review and Meta-regression

The all-polyethylene components were equivalent to metal-backed components regarding revision rates and clinical scores and had better fixation (RSA) than the metal- backed components.

Bariatric Orthopaedics: Total Knee Arthroplasty in Super-obese Patients (BMI > 50 kg/m2). Survivorship and Complications

Complications were more frequent and functional outcomes were significantly lower in super-obese patients, compared with a matched group of patients who had a BMI less than 30 kg/m2.

Influence of Body Mass Index (BMI) on Functional Improvements at 3 Years Following Total Knee Replacement: A Retrospective Cohort Study

Obese and morbidly obese patients gain as much functional benefit from total knee replacement as patients with lesser body mass indexes, but these patients are less satisfied with their knee replacement and almost a third would not have the operation again.



All-polyethylene and Metal-backed Tibias Have Similar Outcomes at 10 Years: A Randomized Level I Evidence Study

The 8- to 12-year followup of the earlier reported prospective randomized comparison of a modern congruent all-polyethylene tibial component with a modular metal-backed tIBial component of the same design found that the contemporary all- polyethyleneTBI component functioned equivalently to its monoblock counterpart and was less costly.

A Randomized Comparison of All-Polyethylene and Metal-Backed Tibial Components

Total knee arthroplasty with a well-designed, contemporary congruent all-polyethylene tibial component functions equivalently to its metal-backed tibia counterpart at 3-to 5-year followup in this patient population, and is less costly ($675).

Excellent Survival of All-polyethylene Tibial Components in a Community Joint Registry

Total knee arthroplasty with one of the three contemporary congruent all-polyethylene tibia designs used in this registry performed extremely well in this population; savings for this group (compared to those with a metal-backed component) was estimated at $729 per case.

Matched-pair analysis of all-polyethylene versus metal-backed tibial components.

The use of a more cost-effective all-polyethylene tibial component in elderly patients (>70 years old) who are not likely to need the versatility of exchange of a modular polyethylene insert because of wear is advocated.

All-polyethylene compared with metal-backed tibial components in total knee arthroplasty at ten years. A prospective, randomized controlled trial.

The long-term results demonstrate excellent survivorship, with revision as the end point, for both the metal-backed and the all-polyethylene tibial component designs with no differences noted between the two.

Metal-Backed and All-Polyethylene Tibial Components in Total Knee Replacement

Metal backing and modularity were added to the Press Fit Condylar ® total knee replacement design to improve fixation durability, however, the superiority of the modular metal-backed implants remains in question.

Survivorship comparison of all-polyethylene and metal-backed tibial components in cruciate-substituting total knee arthroplasty—Chinese experience

The results of this series of TKA using all-polyethylene tibial components in Chinese people are comparable to the satisfactory results of other reported all- polyethylene series whose patients are mainly Western people.
